Chemical Structure

1,4-Dihydroxy-6,7-dimethylanthracene-9,10-dione CAS 3056-98-2 chemical structure

Description

The occurrence of 1,4-Dihydroxy-6,7-dimethylanthracene-9,10-dione is closely related to a flavonoid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1,4-Dihydroxy-6,7-dimethylanthracene-9,10-dione (CAS 3056-98-2) is a high-purity analytical reference standard with the molecular formula C16H12O4 and a molecular weight of 268.26 g/mol.

Based on its molecular formula C16H12O4, 1,4-Dihydroxy-6,7-dimethylanthracene-9,10-dione contains a flavonoid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 268.26 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
